TISA PROTOCOL
This protocol can be used to get a calculated price and weight having sent the cost per kg. It is used
in Modes 3, 4 and 5 in the following logic:
MODE 3 | Only responds to requests;
MODE 4 | Sends information when stable, and responds to requests;
MODE 5 | Streams information and responds to requests.
